add up the kernel cod and reserved parts of the dmesg and at that to your 125 ... does that come close to the physical?

# dmesg | grep Memory
Memory: 131958564k/135266304k available (2457k kernel code, 2253348k reserved, 1246k data, 196k init)
# grep Mem /proc/meminfo
MemTotal:     131962124 kB
MemFree:       5651632 kB

So dmesg is showing 125GB available out of 129MB.
/proc/meminfo is showing a total of 125GB.

# omreport chassis memory 
... cut
Attributes     : Installed Capacity
Memory Array 1 : 131072  MB

So the chassis is reporting 128GB

# free -k
             total       used       free     shared    buffers     cached
Mem:     131962124  128011236    3950888          0     715880   62539312

Linux is reporting 125GB both at boot and during the running of the OS.

Where has the remaining RAM gone ? 

Thanks
Nick .
